Question

electric field at a point varies as r^0 for​

Answer 1

Infinite sheet

Electric field due to infinite sheet = sigma/2€

which is independent of r i.e. it varies as r^0

Answer 2

Electric field at a point varies as r^0 for​ infinite sheet .

We need to find in which electric field at any point varies as $r^0$ .

We know , in most of the case electric field varies as $r^{-1}$ or $r^{-2}$ .

But , we know in infinite sheet electric field at any point is given by :

$E=\dfrac{\sigma}{2 \epsilon_o}$

Here , we can see that electric field does not depend on distance between the point where we have to calculate the electric field .

Therefore , it is proportional to $r^0$ .

Hence , this is the required solution .
